ABSTRACT
OBJECTIVE: To establish a fingerprint analysis method for quality control of Panax quinquefolium from Liuba County in Shanxi Province by RP-HPLC. METHODS: A gradient mobile system was applied in the experiment. The fingerprints of different samples were compared by similarity evaluation software. RESULTS: The similarities among different samlpes were high. 14 peaks were identified as the characteristic fingerprints of Panax quinquefolium. All samples contained the same characteristic peaks, but the content difference of each peak among the samples resulted in the difference of their chromatograms. CONCLUSIONS: This method is precise with good repeatability and good baseline separation of all the chromatographic peaks, so it can be effectively used to assess the quality of Panax quinquefolium.
